I don't intend this to be an advertisement... but I purchase all of my TV's at "The Big Screen Store" because they look up online pricing, match it, then offer double the manufacturers warranty at no cost and $50 to double that... so for $50, I quadrupled my 1 year manufacturers warranty on a 55" Samsung 4k 120hz LED tv, and I got the TV at the same price as Amazon.
Now, you may not live near a Big Screen Store and if that's the case, I apologize.
